We can't change the fact that RB has a faster substring

There are lots of articles on fast string searching, e.g.


http://www.grouse.com.au/ggrep/string.html

http://www.arstdesign.com/articles/fastsearch.html

http://www.cs.utexas.edu/users/moore/best-ideas/string-searching/

http://www.dcc.uchile.cl/~gnavarro/software/

I think it would be time well spent for RR to implement at least the "Self-Tuning Boyer-Moore string search" at http://www.grouse.com.au/ggrep/stbm.c.html

If you're running it once, maybe you don't care. But if it's in a loop of 100 or 1000 then there's a big difference.


Anything that RR can do to speed up low-level routines, the better off we'll all be.
